4000 Horizon Way, Irving

Lewisville-based Nationstar Mortgage is expanding its Irving operations, adding 105,559 square feet to its lease at 4000 Horizon Way. The company will now occupy the entire 293,000-square-foot building.

Doug Gordon, corporate vice president of real estate and facilities for Nationstar, said the company has doubled in size in the past year and expects the trend to continue.

“We need more operational capacity to serve our markets and sustain our growth,” he said in a statement.

Terry Quinn with Cresa Dallas represented Nationstar in its new lease. CBRE’s Ann Huntington and Dennis Barnes represented the landlord, First Tennessee Bank National Association of Memphis.

Huntington said the expansion was inked within eight months of signing the original lease.
